Procedure

Icotinib (1000 mg) was added into 100 mL reaction flask and dissolved with 60 mL of methanol. The concentrated hydrochloric acid was added dropwise while stirring till PH was adjusted to 2.0. After its completion, the reaction mixture was filtered to give crude product. The crude product was further purified by recrystallization with isopropyl alcohol to give Icotinib hydrochloride (1000 mg).
